  kvm hangs occasionally when switching out of the qemu console

Status in QEMU:
Status in qemu package in Ubuntu:

Bug description:
  To recreate (although this does *NOT* fail most of the time alas):

  1) press "ctrl-alt-2" to switch to the qemu console.
  2) type say "sendkey ctrl-alt-f1"
  3) press "ctrl-alt-1".

  Expected outcome: Switch to tty1 in the VM.

  Actual outcome: No switch to tty1 in the VM. and qemu console
  unresponsive to any keyboard input.

  Rather a vague problem description I'm afraid but this has happened to me 3 
times recently. No crash and no excessive CPU is observed.

  I'll grab an strace when it happens again and attach...
